Infix notation to PharmML math online converter

The infix2pharmml converter translates expressions from the usual mathematical infix notation into the corresponding PharmML markup. PharmML is a markup for pharmacometrics models developed by the DDMoRe consortium.

Converter version 0.6.x. The output should be compliant with PharmML version 0.6.

Quickstart

This is an online version of the converter. For details, a full list of the converter's features and limitations, and source code, see the project's README and the infix2pharmml project page at SourceForge.

The converter works in either single-statement or stand-alone model mode.

In single-statement mode it converts a variety of statement types into the equivalent PharmML constructs, one at a time. The user is responsible of combining them, and supplying boilerplate code in order to get a fully-functional (e.g., XML-valid) model.
In stand-alone mode it creates a mostly ready-to-run model (encompassing only structural equations). In this mode, several statements can be provided separated by semicolons. Statement types are restricted to variable and derivative variable definitions. Stand-alone mode is intended to jump-start development, and it is not a full-fledged modeling tool.
